Image forming apparatus and image controlling method

Abstract

An image forming apparatus includes an image bearing member; toner image formation means for forming a toner image on the image bearing member; removing means for removing deposited matter deposited on the image bearing member; detecting means for detecting a toner image to be detected, formed on the toner image formation means; control means for controlling a toner image forming condition of the toner image forming means in accordance with a result of detection of the toner image to be detected by the detecting means; the apparatus being operable in a mode in which the removing means operates to remove the deposition, and the detecting means operates to detect the toner image to be detected, executing means for executing an operation in the mode; and an operating portion for manually starting execution of the operation in the mode by the executing means.

1. An image forming apparatus comprising:
 a rotatable image bearing member for bearing a toner image; 
 toner image forming means for forming a toner image on said image bearing member; 
 transferring means for transferring the toner image formed on said image bearing member onto a recording material; 
 a cleaning member contacted to said image bearing member to remove toner from said image bearing member after image transfer; 
 a detecting member for detecting a detection toner image formed on said image bearing member; 
 an adjusting portion for adjusting a toner image forming condition of said toner image forming means in accordance with a result of detection by said detecting member; 
 an executing portion for executing an operation in a recovery mode in a state in which said cleaning member is in contact with said image bearing member, wherein in the recovery mode, said executing means (i) starts rotation of said image bearing member, (ii) then causes said toner image forming means to form a band of toner having a width of a maximum image area measured in a direction perpendicular to a moving direction of said image bearing member, (iii) then causes said toner image forming means to form the detection toner image, and (iv) then causes said detecting member to detect the detection toner image for adjusting the image forming condition; and 
 an input portion for causing said executing portion to execute the operation in the recovery mode. 
 
     
     
       2. An apparatus according to  claim 1 , further comprising an operating portion provided with said input portion. 
     
     
       3. An apparatus according to  claim 1 , wherein said adjusting portion adjusts the toner image forming condition on the basis of detection of the detection toner image formed during the execution of the operation in the recovery mode. 
     
     
       4. An apparatus according to  claim 1 , wherein said adjusting portion adjusts the toner image forming condition on the basis of detection of a position of the detection toner image formed during the execution of the operation in the recovery mode. 
     
     
       5. An apparatus according to  claim 1 , further comprising a selector for selecting formation of the detection toner image during the execution of the operation in the recovery mode.
